Fantastic mate, well done.

[inverted]

Yep.....it works

[NoGi]

New version of this poster coming soon. If there are any errors with the current poster please let me know as it's being used as a template for the new one.

[jayc]

You might want to mention somewhere on the poster that Caridina logemanni's common name is Crystal Red Shrimp (CRS) ... for the newbies.

[NoGi]

Is it only CRS? What about CBS?

[jayc]

Oh yeah, CBS too, but your picture is of CRS

[NoGi]

Yeah because more people can relate it the reds

[NoGi]

You might want to mention somewhere on the poster that Caridina logemanni's common name is Crystal Red Shrimp (CRS) ... for the newbies.

 

How about something like:

 

Commonly known as the Crystal Red Shrimp (CRS) or Crystal Black Shrimp (CBS), this freshwater dwarf species is popular amongst shrimp keepers around the world. They prefer cooler water temperatures (21-25 degrees Celsius) and a pH range of 6.0-7.0. 

[jayc]

Sounds great!

 

The new logo would look sweet on the poster.

[NoGi]

Yeah. Have I got the temp and pH range about right?

[jayc]

Yeah. Have I got the temp and pH range about right?

 

Yes you got it right.

[NoGi]

Any other vitals like avg lifespan, length etc people can provide?

[jayc]

Avg lifespan = 1-2 years.

Avg Length = 1.5 - 2 cm

 

Other water parameters:

gH should be between 4-6 and kH should be between 1-2.

TDS = 140-160

Yes, they might be able to survive at GH/KH and TDS outside those, but extremes are to be avoided, so this is a safe range.

Nice poster, looking forward to the new version. I would add that this is about pattern only. Since quality has nothing to do with pattern in my opinion.

 

About the params: I agree with you most part, except:

KH is around 0 in my tanks. Seems they don't need carbonate and bicarbonate, but that's just my own experience. Can't say it's a fact.

TDS range is also very tight, I would say something like 100 - 300 TDS would be fine too since dissolved organic waste is also in this number, so you can't really say exact numbers I believe. It depents on a lot of factors.

And PH: 5.5 -> 7.0 is preferred.

Maybe temperature too: 18 -> 24 celcius.

I agree it would be good to mention something about quality and pattern. If pattern alone equaled high grade I would have a tank full of SSS!

[jayc]

How do you measure KH?

KH might look like 0, but I bet it's not actually 0. 

KH 0 or 1 is very similar on test kits. 

But I have no issues with using KH range 0-2 in a poster as an introduction to new shrimpkeepers. 

 

If we say GH range is 4-6, then a 300 TDS range is unrealistic. 

It's very hard, especially for a person new to the hobby, to maintain GH 4-6, while TDS is way over 200.

A TDS range of 100-200 would be more realistic. I mentioned a tight range because I live by the motto "Aim small, miss small". 

 

And I agree with your other parameters.

[NoGi]

Ok, the revised text I've sent to my guy is as follows:

 

Commonly known as the Crystal Red Shrimp (CRS) or Crystal Black Shrimp (CBS), this freshwater dwarf species is popular amongst shrimp keepers around the world. Growing up to 1.5 – 2cm long, the Caridina logemanni has an average lifespan of  1 – 2 years and generally do well under the following water conditions:

Temp: 18 - 24 degrees Celsius

pH: 5.5 - 7.0

gH:  4 - 6

TDS: 100 - 300

They may survive outside of these parameters but these are considered to be a safe range and extremes are to be avoided.

 

and to put this somewhere:

 

This chart is to assist with pattern classification only, it does not describe the quality of the shrimp. The quality is determined by factors that are not in consideration here.

[NoGi]

I'll tweak the parameters once I know how the chart will look with this info

[Shrimpmaster]

How do you measure KH?

KH might look like 0, but I bet it's not actually 0. 

KH 0 or 1 is very similar on test kits. 

But I have no issues with using KH range 0-2 in a poster as an introduction to new shrimpkeepers. 

Good point, 0-2 is even better.

If we say GH range is 4-6, then a 300 TDS range is unrealistic.

It's very hard, especially for a person new to the hobby, to maintain GH 4-6, while TDS is way over 200.

A TDS range of 100-200 would be more realistic. I mentioned a tight range because I live by the motto "Aim small, miss small".

What I've read about this, is that for example waste that is deconstructed by bacteria is dissolved into the water column. So this also add up the TDS number. So I thought you could have a TDS of 400, but still a GH of 6. When you create fresh water, like Osmose with mineral salt, than indeed it's impossible to create a high TDS and low GH. Than the GH and TDS are always in relation to each other. But in the tank, TDS can rise without GH is rising.

So I also use TDS to see if I do enough water replacements. When TDS keeps rising, it's a sign I should do a little bigger percentage when doing water changes.

Ok, the revised text I've sent to my guy is as follows:...

 

..a couple of edits you might like to consider.

 

General Hardness is GH not gH

 

...be consistent across parameters.  ie don't spell out "degrees Celsius" if you don't intend to also use "German Degrees") - personally I like °C

 

GH and KH have units also.  dGH, dKH, °dH or German Degrees

 

TDS also has units  - mg/L or ppm

[NoGi]

Cheers, will fix up. I did ask for °C, just couldn't find it when typing my post lol

OK, first post has been updated with the draft poster. Comments, corrections welcomed.

[jayc]

FAN-TAS-TIC!!!!!

[fishmosy]

Awesome. I would take out the "The" infront of Caridina longemani in the line that talks about how old the shrimp get.
